Mapping

Select the simulation channel that you want the shader to use as input.

Blur the field before using it as shader input.

This function curve (f-curve) allows you to map the input values to an intensity curve before they are used to determine the smoke's color and opacity. A linear 0 to 1 gradient will leave the values unchanged.

To edit the Mapping, click on the curve to open the f-curve editor. See the section on using the f-curve editor for details.

To use a separate channel to control the smoke's opacity, select it here. If you use it, the first channel, smoothing and mapping parameters will only control the smoke color. The Smoothing and Mapping parameters below will affect only the opacity.
